HID 921NNPNEK2038A – Frequently Asked Questions

1) Will the HID iCLASS SE RK40 keypad reader fit a standard single gang wall switch box?
Yes. The iCLASS SE RK40 is built for standard wall switch mounting, and the reader body measures 3.3 x 4.8 x 1.1 inches (8.5 x 12.2 x 2.8 cm). That footprint covers a single gang box and leaves the keypad and card target on the face. If you are mounting on a narrow mullion or a door frame rather than a wall box, this is the wrong form factor and you want a mullion style reader instead.
2) Will an SDC IPRW proximity reader work as a substitute for the iCLASS SE RK40 keypad reader?
They read different credentials and communicate differently, so they are not drop-in equivalents. The iCLASS SE RK40 is a 13.56 MHz reader that supports iCLASS Seos, iCLASS SE, iCLASS, MiFare Classic and MiFare DESFire EV1 credentials and uses OSDP for reader-to-controller communication. The SDC IPRW Series is a Wiegand proximity reader with 125KHz HID compatibility, so it reads 125 kHz prox credentials and reports on Wiegand. If the site is already carrying 13.56 MHz smart cards or HID Mobile Access, the RK40 is the reader that matches those credentials; if the site is still on 125 kHz prox cards and the panel takes Wiegand, the IPRW matches that instead.
3) My access control panel only has Wiegand inputs. Does the iCLASS SE RK40 fit, or do I need a different reader?
The iCLASS SE RK40 is specified for OSDP, the open supervised device protocol used for secure communication between reader and controller, so the head end needs to accept OSDP. A panel wired for Wiegand pairs with a Wiegand-output reader such as the SDC IPRW Series, which is a Wiegand proximity reader with 125KHz HID compatibility. Confirm the panel port type before ordering, since the wiring and the credential technology change together between these two readers.
4) Do I need a keypad reader or is a card only reader enough for my door?
The keypad matters when the opening needs two factors. The RK40 is built for multi-factor authentication door applications, so a user presents a credential and enters a PIN, which is what you want on a server room, a pharmacy, a cash office, or any door where a lost badge alone should not open it. On a general office or corridor door where badge only entry is acceptable, a reader without a keypad does the same job with less to install and less for users to forget.
5) What is the difference between iCLASS SE and plain iCLASS on the RK40, and does it matter for security?
iCLASS SE adds the secure identity object (SIO) data model, which puts an additional layer of encryption around the identity data on the credential, on top of the card technology itself. The RK40 reads both, so an existing iCLASS card population keeps working while you issue SE or Seos credentials going forward. That matters if you are standardizing a portfolio: you do not have to reissue every badge on the day the readers change.
6) Can I use the HID RK40 reader with employee phones instead of issuing cards?
Yes. The RK40 supports mobile devices as a credential form factor alongside cards and fobs, and it is configurable to support HID Mobile Access. So a mixed population works: contractors on plastic fobs, staff on phones, all on the same reader. The mobile side has to be set up on the HID Mobile Access service, the reader alone does not provision phones.
7) Which model number do I order for the black HID iCLASS SE RK40 keypad reader?
The part is HID model 921NNPNEK2038A, the single gang iCLASS SE RK40 keypad reader with a black body, 13.56 MHz high security configuration, OSDP output, pigtail termination, revision E. The configuration is baked into that number, so quote it exactly when you are matching readers already installed on a site, a different suffix can mean a Wiegand output or a different keying configuration entirely.
8) I only need card-only entry at this door, no PIN. What reader should I use instead of the RK40?
The iCLASS SE RK40 is a keypad reader built for multi-factor authentication doors, where the user presents a credential and enters a PIN. For an opening that needs credential-only entry, the SDC IPRW Series is a proximity reader without a keypad, reading 125 kHz prox credentials with HID compatibility and reporting on Wiegand. Choose based on the credential the building already issues and what the controller accepts: the RK40 covers 13.56 MHz smart cards and mobile plus PIN entry over OSDP, the IPRW covers 125 kHz prox over Wiegand.
9) Does the SDC IPRW support mobile credentials the way the HID RK40 does?
The iCLASS SE RK40 is configurable to support HID Mobile Access and reads a variety of form factors including cards, fobs and mobile devices, with the iCLASS SE secure identity object data model adding a layer of encryption over the identity data. The SDC IPRW Series is described as a proximity reader with 125KHz HID compatibility on a Wiegand output, which is the classic prox card and fob path. For a rollout where phones are the credential, the RK40 is the reader carrying that capability.
